afghanistan is just one of the foreign policy hurdles facing the president in his second term. here to break down all of those is retired army colonel and medal of honor recipient jack jacobs. is he also an msnbc military analyst and the author of basic surviving boot camp and basic training. jack, it's good to see you here, and as we talk about what we're watching in afghanistan, based on this recent news, obviously this has to be a factor in what the president and the advisors, his generals, tell him about the withdrawal. what does if mean for the contemplation of that early withdrawal from afghanistan? >> well, the irony is that as we reduce combat troops, incidents like this, that will continue in any case, then become more prominent, but no matter how many combat troops we actually withdraw from afghanistan, in the end the president is going to decide to leave a certain number of advisors there for a certain period of time and these attacks, these green on blue attacks are going to continue, and they're going to become more prominent as we withdraw american forces. fwloo w
